Manchester United Double winner Paul Ince has hit out at the club for allowing Borussia Dortmund to sign Erling Haaland.

Ince insists players of that quality cannot be overlooked if United wish to return to football's top table.

"If they want to close the gap on Manchester City and Liverpool then they need a world class striker," he told Goal.

"They had the chance with Haaland, the young kid who went to Dortmund, that was sad really. He is a very, very good player who can improve and you can't let people like that slip through the net."

Ince maintains Ole Gunnar Solskjaer should have been allowed to sign his former Molde striker.

"That was disappointing that they couldn't get him. They have got to have someone in who gets 20-25 goals a season.

"There are players who Ole will still feel should not be there next year. There will be more players leaving and more coming in. I think you have to get the right balance."
